CIGARETTE MAKING MACHINE Filed Dec. '7. 1951 3 Sheets-Sheet 3 INVENTOR flfl/VG GEE United States Patent 2,714,383 CIGARETTE MAKING MACHINE Ming Gee, Boston, Mass. Application December 7, 1951, Serial No. 260,374 2 Claims. (Cl. 131--70) This invention relates to cigarette making machines, and more particularly to a machine arranged to pack tobacco into a tubular paper cylindrical container to form a cigarette.

A main object of the invention is to provide a novel and improved cigarette making machine which is simple in construction, which is easy to operate, and which is very compact in size.

A further object of the invention is to provide an improved cigarette making machine which is relatively inexpensive to manufacture, which is durable in construction, which is reliable in operation, and which involves a simple manual operation to form a cigarette.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 11 is a front end elevational view of the machine of Figure 1 with the tobacco receiving hopper removed.

Figure 12 is a front end elevational view of the machine of Figure 1 with the operating handle at the end of its operating stroke, as in Figure 3.

The rectangular main body portion of the housing 21 27, defining the top wall of said housing. The housing 21 is formed adjacent a forward corner thereof, for example, adjacent the left forward corner, as viewed in Figure 1, with an elonfoldable tobacco receptacle, shown at 30, is adapted to be slidably received, the guides 29, 29

being arranged to receive the edges of a bottom plate 31 provided on the Figure 13 is an enlarged cross sectional detail View l taken on the line 13-13 of Figure 12 andshowing the tobacco-receiving hopper mounted in its guides, the tobacco-receiving hopper being shown in folded position.

Figure 14 is a perspective detail view of the cigarette ejecting plunger employed in the machine of Figure 1.

Referring to the drawings, the cigarette making machine is designated generally at 20 and comprises a supporting housing of rectangular shape shown at 21, having the base flanges 22 extending around its perimeter. Secured to the margin of the base flange 22 at the forward the longitudinal marginal portion an arcuate cam slot 54 formed in Figures 1 and 2, 29, 29 are arranged to receive the tobacco on the top end of the shaft 33.

fits snugly within the channel-shaped handle 32, as shown in Figure 9,

urginlg the plate member 35 against the web of said 27 and spaced laterally from one edge of the slot 28 to define block at 49, 49 are additional link pair of link arms 43 to a longitudinally at its end arms 50, 50. Each and 50 is pivotally connected at 51 extending arm 52 which is provided with a follower element 53 extending through the cam 39; The

Designated at 55 is a short conduit member secured in the end wall of the housing 21 in alignment with the cavity defined between the grooved edge of block 45 and the flange 44 when the block 45 is in the position The conduit 55 is adapted to receive a paper cigarette tube 56 telescoped thereon, into which the tobacco compressed in the cavity is injected, as will be presently described. Designated at 57 is a hollow elongated guide sleeve rigidly secured beneath the top plate 27 in alignment with the tube 55 on the opposite side of the cavity defined between flange 44 and the groove 46, above mentioned. Slidably mounted in the sleeve 57 is a plunger 58. The sleeve 57 is formed with an elongated longitudinal slot 59. Connected to the plunger 58 by a pin 60 extending through slot 59 is a link arm 61. The link arm 61 is pivotally connected at 62 to the end of arm 40. The plunger 58 is formed at its left end, as viewed in Figure 9 with a reduced, thin channeled extension 63 which is normally disposed adjacent to the flange 44, as shown in Figure 7, said channeled extension opposing the groove 46, as is clearly shown in Figure 7.

As the cam 39 is rotated by the handle 32, in a counterclockwise direction, as viewed in Figure 4, and as above explained, the pin 41 engages the arm 40 at the end of the initial portion of the rotation stroke of arm 32, namely, through approximately 120 counterclockwise, and the pin 41 then ,acts against the arm 40, causing the arm 40 to be rotated counterclockwise, whereby the plunger 58 is moved toward and through the cavity defined between the grooved end of the block 45 and flange 44. The earn 39 is formed with a continuation .64 of the slot 54, the slot portion 64 being arcuate in shape and having its center at the axis of shaft 33, whereby it causes no motion of the follower 53 as the operating handle 32 is rotated to the concluding portion of its stroke.

It will be apparent that the plunger 58 causes the compressed tobacco in the cavity between the block 45 and flange 44 to be injected through the conduit 55 into the cigarette tube 56 responsive to the rotation of the operating handle 32 through the second portion of its stroke, namely through that portion subsequent to the engagement of the pin 41 with the arm 40.

, Pivoted at 65 to the bottom surface of the receiving plate 43 is a lever 66 having one arm thereof, shown at 67, projecting through a slot in the end wall of the housing 21 to a position adjacent the conduit 55. Se.- cnredto the end of the arm 67 is a vertical pin 68 on which is mounted a roller 69. A coiled spring 70 connects the arm 67 to the adjacent front longitudinal wall of the housing 21 and biases the roller 69 toward engagement with the conduit 55. The lever 66 has an arcuate extension 72 which extends over and adjacent to the arm 40. The arm 40 has secured thereto an upstanding pin 73 which is engag'eable with the inner edge of the extension 72, as shown in Figure 5. The extension 72 is biased into engagement with the pin 73 by the action of the spring 70. Said extension 72 is formed with a shouldered portion 74 which is arranged to engage pin 73 so as to normally maintain the roller member 69 spaced slightly from the conduit 55. During the rotation of the arm 40, as the pin 73 leaves the shouldered portion 74, the lever .66 is released and the roller member 69 comes into clamping engagement with the conduit 55. Therefore, a cigarette tube 56 may be freely engaged on the conduit 55 without interference from the roller 69 when the device is in its normal position, shown in Figure 1. However, hortly after the operating handle 2 e e ude L. itia or on of it stroke, namely, the portion in which the tobacco is compressed in the tobacco-receiving cayity, the clamping roller 69 is forced a ainst he end' o the c are e t be ho i tube h e eehdu t .55 duri th in'i e eh e tebaeee into the tube by the plunger 58, as above described.

Adjustably secured on the lever 66 by the screw 71 is the slotted adjustable cam element 75 which is arranged to be engaged by the pin 73 at the end of the operating stroke ot the handle 32. When the pin 73 engages the rising portion 76 of the cam element 75, the lever 66 is rotated counterclockwise, as viewed in Figure 5, and as shown in Figure 6, causing the clamping roller 69 to be moved away from the conduit 55 and releasing the cigarette .tube 56, whereby the completed cigarette may be removed from the conduit member 55.

It will be readily apparent that in operation of the device, it is merely necessary to mount a cigarette tube 56 on the conduit member 55, move the required amount of tobacco through the slot 28 onto the receiving plate 43, and then to rotate the handle 32 clockwise from the position thereof shown in Figure 1 to the position thereof shown in Figure 3. The tobacco is compressed during the first portion of the stroke of the handle 32, namely, through approximately of clockwise rotation thereof, as viewed in Figure 1, and the compressed tobacco is then injected into the cigarette tube by the action of the'plunger 58 during the remainder of the rotational stroke of the handle. The cigarette tube is clamped to the conduit 55 during the time that the plunger 58 is injecting the tobacco into the tube, and the cigarette tube is 'released at the conclusion of the injection stroke of said plunger by the engagement of the pin 73 with the release cam 75, as above described. The parts re turn to their normal positions when the operating handle is returned to the starting position thereof shown in Figure 1. j

The tobacco container 30 may be of any suitable construction, such as of a foldable construction having the inwardly foldable side walls 77, 77 and the inwardly el ehle re r end W ll t e s e alls 77, 77 bein foldable over the end wall 78 when the container is in its collapsed or folded position.
